Empress Frederick felt that Alice and her children were in need of her assistance in many ways. I think Vicky, on rare occasion, felt somewhat put-out by this, but all in all was very generous with money and emotional support. Vicky gave great effort to seeing that her children and their cousins had a good relationship and were together frequently. In so doing, Vicky was attentive and "Motherly" to Alice's children. Queen Victoria had a special spot in her heart of Alix, so this may, repeat may, have caused Vicky some level of jealous distance, but no such evidence exists, I believe.
